| Description: |
The St. Louis River is the second largest tributary to Lake Superior. The lower estuary culminates in the Duluth-Superior Harbor, which is one of the more heavily used ports on the Great Lakes. In 1987, concerns over environmental quality conditions prompted the designation of the lower St. Louis River as one of 43 Great Lakes Areas of Concern (AOCs).

Exa was responsible for the conducting the database portions of Phases III and IV: |
|
> |
In Phase III, additional GIS-based sediment quality data were reviewed for quality and added to the database. |
|
> |
In Phase IV, the database structure was updated include benthic infaunal data, and new infaunal data were added. |
|
> |
In Phase IV, a query interface was developed to improve access to the database. |
|
> |
In both phases, user documentation, as well as summary tables and figures were generated. |
